It's great that you found SR. There is a lot of support here. You are not alone.
You did a great thing by letting go of that guy. He sounds like he'd only pull you down. I had to let go of someone like that myself. Not easy but you will feel better about yourself and your recovery without that person pulling you down.
It gets better every day. It doesn't always feel like it but know that each day you don't drink, you are one step closer in your healing.
Stick around SR, post, read, and just talk about whatever is on your mind.
This place is full of people who have been through or are going through what you are dealing with now so post and talk all you want.
